I wish there was on option to either disable this choice, or make the default "stay on".

My old 60csx never had this feature, and after 10 years, I cannot think of a single occasion that I wish it had shutdown after I disconnected the external power.

Sometimes, it could cause me to lose track recording. Many times, I take my GPS in the car to record my travels, but since I know where I'm going I don't need it for guidance, and I just have it plugged-in and either on the back seat, or in the centre console. On these occasions, the 66st will turn itself off when I stop the car, and I'll probably not remember to turn it back on when I get back in my car to continue the journey - resulting in me losing track recordings.

The device doesn’t know whether or not the plug was pulled, or fell out unintentionally (ie. motorbiking or similar activity).
I can understand the reason for it, but maybe option would be nice.
60csx also had a kick ass power connector that isn’t just falling out.

My 60CSx has a countdown timer when external power is lost. A message pops up saying external power is lost and 30 seconds starts ticking down. Pressing any button during that 30 seconds keeps it powered on but if no button is pressed, powers off when zero is reached.

That is very interesting - mine just beeps and pops-up a message saying external power has been lost - but doesn't start a timer to shutdown. In the "System" options, it has choices for External Power Lost of: "Turn Off" or "Stay On"

FWIW - My 60CSx is one of the originals, got it soon after release. And it has whatever the last, (latest), firmware/software update would have been.
